HOLLOW PUNCH.

Application filed July 27,

This invention relates to a punch adapted to be used more particularlyfor cutting the photographs of licensed chauffeurs from photographiccards preparatory to attaching the same to the chauffeurs license asrequired for taxicab operators, but .obviously may be used for manyother purposes where visibility of the portion of the card to be cut outis necessary.

In the preparation of these licenses itis customary to make relativelysmall photographs of the facial expressions of the licensee to beattached to the license and the main object of the present invention isto provide a simple and comparatively inexpensive device for punchingout the portion of the photographic card bearing the facial expressionsof the licensee in such manner that the main features may be centrallylocated upon the cut-out portion of the card by making the male punchtubular so that the portion of the card to be cut-out may be visibly andaccurately registered with the opening through the punch.

Another object is to provide a hollow lower die with an opening in oneside thereof through which the cutout portion of the card may bewithdrawn.

Other objects and uses relating to specific parts of the device will bebrought out in the following description.

In the drawings Figure 1 is a top plan of my improved punch on a reducedscale.

Figure 2 is an enlarged side elevation, partly in section, in the plane.of line 2- 2, Figure 1.

Figure 3 is a front face view of the device shown in Figure 2. I

Figure 4.- is a perspective view of the do taehed tubular plunger.

As illustrated, this device comprises a onepiece U-shaped frame 1preferably of cast iron or equivalent material forming lower and upperarms -2- and 3 and an intervening horizontal slot 4 both arms beingdisposed in substantially horizontal planes.

The lower face of the frame 1--is substantially flat and adapted to restupon a bench or other available support, but ohviously may be clamped ina vise, if desired.

1927. Serial N0. 208,801.

The front ends of the arms -2 and 37 are mainly cylindrical in top planand provided with co-aXial cylindrical openings 5 and 6 therethroughfrom top to bottom, the lower portion of the frontend of the arm 2 beingcut away to form an opening 7 to ,communicate with the adjacent portionof the cylindrical opening and allow the cut-away portions of the cardsto be withdrawn by hand therethrough.

The adjacent sides of the cylindrical portions of the arms -2- and 3 areprovided with cylindrical bosses -8- and 9-.- having substantiallyflatparallel faces in spaced relation to form a guide opening 4t betweenthem for receiving and guiding the card to be punched between the lowerand upper dies, presently described, the guide opening -4- forming anextension of the opening 4- but of less vertical depth than theremaining portions of the opening at the rear of the bosses '-8- and 9-.

A relatively small axial length of the upper portion of the opening -5-is reduced in diameter to form a cylindrical die -10 having itsperipheral wall co-axial with the opening .5- and more or less hardenedto form a cutting or shearing edge adapted to cooperate with thepunching .die, presently described, for removing the desired portion ofthe card when the punching die is depressed.

A relatively small axial length of the lower portion of the opening 6'-in the upper arm is reduced to about the same diameter as the peripheralwall of the female die -10 to form a guide for the lower end of atubular punching die 11- and also forming an annular shoulder -12- forsupporting the lower end of a coiled spring which surrounds theintermediate portion of the outer periphery of the plunger 1;1 fornormally elevating the same.

As previously stated the'male die or vertically reciprocating plunger-1-1 is cylindrical and tubular and is provided with a coaxialcylindrical. opening -14, therethrough from end to end of slightly lessdiameter than the diameter of the lower female die ;10 to afford greatervisibility of the portion of the card as --owhich is inserted in theguide slot .4'- thus perll above the upper face of the arm -3-- isprovided with an outwardly projecting annular flange l6-- adapted tocooperate with the underlying upper face of the arm 3 for limiting thedownward movement of the plunger. the uppeface of the plunger beingdisposed mainly in a horizontal plane at right angles to the axisthereof and rounded at its outer edges to be engaged by pressure'of thehand thereon for depressing said plunger into cooperative cuttingengagement with the lower die 1.0 for removing the alined portion of thecard a-.

The peripheral portion of the plunger 11 between. the shoulder -15- andannular flange -16 is cylindrical and of substantially the same diameteras the opening -6- in the upper portion of the arm '3' for guiding theplunger in its axial movement.

The lower face -17- of the plunger -11- adjacent the die 10- is disposedin a plane diagonal to the axis of the plunger or at a slight angle toits direction of movement so that one portion thereof, in this instancethe front port-ion, will be lower than the remaining portions toconstitute a shearing edge adapted to cooperate with the inner peripheryof the die -10 for severing the registering of the card a-- when theplunger die 11- is depressed into the lower die 10-.

The front face of the lower portion of the arm -3- is slightly cut awayby beveling at -18 beyond the corresponding face of the lower arm 2 sothat the upper face of the front portion of the arm. -2-- constitutes aledge or feed across which the card --amay be fed by hand when insertingit into the slot -4'-- and between the dies --10- and 11-.

The front face of the die 11 below the flange --16- is provided with alengthwise slot 19- while the corresponding portion of the arm -3- isprovided with a screw -20 normally projecting into the slot 19- andadapted to engage the entire walls thereof for limiting the reciprocalmovement of the plunger -11-.

It is evident from the foregoing description that the screw -20 may bewithdrawn out of the path of movement of the adjacent sides of theplunger -1lto perinit the insertion and removal of said. plunger intoand out of the opening -6- in the arm 3.

Operation.

The photographic card as *abearing the facial photograph of a licenseddriver of motor vehicles is inserted in the slot -'l between theadjacent ends of the dies 10- and 11 until the part of the photograph tobe cut out is visible through the opening 14.- and correctly registeredwith said opening as determined visually by the operator through saidopening whereupon the plunger 11 is depressed by hand with sufficientforce to punch out the registering portion of the card and allow it todrop to the bottom of the opening -5 from which. it may be removed byhand through the opening -7-.

Immediately upon the release of the hand from engagement with theplunger '11- the latter will be returned to its normal upposition by thespring 13- until limited by the stop pin 20.

These operations may be repeated indefinitely upon different portions ofthe same card or upon different cards bearing the pictures of thelicenses. This machine is particularly simple, expeditious and efficientbut obviously may be varied as to form and size of the dies so long asthe upper and lower 'dies are provided with registering openings, onefor the reception of the detached part of the card and the other as asight opening through which the operation of the card to be cutout maybe cor 'ectly registered,

What I claim is 1. In a card punching machine of the characterdescribed, a bifurcated. frame having opposed arms provided withregistering openings therethrough, one of the arms be ing provided witha relatively fixed die, an additional die reciprocally movable in theother opening to cooperate with the firstnamed die for punching aninterposed portion of the card and provided with a sight openingtherethrough from end to end.

2. In a card punching machine of the character described, a bifurcatedframe having opposed arms provided with registering openingstherethrougln one of the arms be ing provided with. a relatively fixeddie, an additional die reciprocally movable in the other opening tocooperate with the firstname'd die for punching an interposed portion ofthe card and provided with a sight opening therethrough from end to end,and having its end adjacent the fixed die disposed in a plane diagonalto the axis thereof.

3. In a card punching machine of the character described, a bifurcatedframe having opposed arms provided with registering openingstherethrough, one of the arms being provided with a relatively fixeddie, an additional die reciprocally movable in the other opening tocooperate with the firstnamed die for punching an interposed portion ofthe card and provided with a sight opening therethrough from end to end,said movable die being adapted to be operated by hand toward the fixeddie, and a spring for returning the movable die.

4. In a card punching machine of the character described, a bifurcatedframe having opposed arms provided with registering openingstherethrough, one of the arms be- 1 ing provided with a relatively fixeddie, an additional die reciprocally movable in the other opening tocooperate with the firstnained die for punching an interposed portion ofthe card and provided with asight opening therethrough from end to end,said movable die being adapted to be operated by hand toward the fixeddie, and a spring for returning the movable die, and means for limitingthe endwise movement of the movable die.

5. In a punch of the character described, a bifurcated frame forminglower and upper arms and a guide slot between them, the lower arm beingprovided with a fixed die in its upper end and an axially extendingopening below the fixed die and provided with a branch opening throughthe peripheral wall thereof, a tubular die reciprocally movable in anopening in the upper arm in alinement with the lower die and adapted tobe depressed by hand into cutting co-action with the fixed die, saidtubular die having its lower face disposed in a plane at an angle to itsaxis to form a shearing edge.

In witness whereof I have hereunto set my hand this 22nd day of July,1927.
